Abstract:
A fail-safe sensor system to provide a positive indication of the proper operation of a sensor system by accounting for the return signals from an active zone and a monitor zone beyond. Search signals, provided by a transducer operating in the transmit mode, are transmitted within an active zone within which objects to be detected are expected to be located. Unreturned search signals are permitted to travel beyond the active zone into a monitor zone beyond and objects in such monitor zone cause return signals which are also employed. A counter feed from a free running clock source is permitted to run up a count whose predetermined limit represents the estimated maximum time period during which a sensor system should operate without contacting an object. Return signals, whether from objects in the active zone or the monitor zone, reset the counter back to zero. The absence of a return signal permits the counter to exceed its predetermined limit and produce an output signal which can be directed to control circuitry, an alarm or logic circuitry to determine if the system is operative.

Abstract:
A printed circuit panel connector comprises an encased heat sink for maintaining all electrical connections to the connector at substantially the same temperature. The heat sink is disposed between a plurality of tubular electrical connector elements adapted to receive corresponding external conductors, and a like plurality of electrical contact elements for making electrical connections between each one of the tubular electrical connector elements and a corresponding terminal adjacent the edge of a printed circuit board. Portions of the contact elements are in spring loaded contact with the heat sink such that the heat sink positively retains the contact elements within the terminal block body and maintains the various tubular electrical connector elements and electrical contact elements at substantially the same temperature.
An electrical terminal block is provided with a plurality of terminal-receiving cavities therein and a corresponding plurality of electrical terminal elements disposed within the terminal-receiving cavities. Each terminal-receiving cavity includes a protruding retention member extending into the terminal-receiving cavity. Each terminal element includes a chamfered key member thereon, which is adapted to be captured and to interlock with a complementary retention member during insertion of the terminal elements into their respective cavities. The retention members and their corresponding cooperatively engaging chamfered key members selectively provide means for securing or facilitating removal of the inserted terminal elements.
